1. FIELD

Provided herein are compositions and methods for treating cancers, inflammatory diseases, rasopathies, and fibrotic disease resulting from aberrant Ras signaling involving Ras, Rac, Rho, and Cdc42 members of the Ras superfamily of proteins through the binding of compounds to the GTP binding domain of these molecules.

2. BACKGROUND

Pathobiology of Cancer

Cancer is characterized primarily by an increase in the number of abnormal cells derived from a given normal tissue, invasion of adjacent tissues by these abnormal cells, or lymphatic or blood-borne spread of malignant cells to regional lymph nodes and to distant sites. Clinical data and molecular biologic studies indicate that cancer is a multistep process that begins with minor preneoplastic changes, which may under certain conditions progress to neoplasia. The neoplastic lesion may evolve clonally and develop an increasing capacity for invasion, growth, metastasis, and heterogeneity, especially under conditions in which the neoplastic cells escape the host's immune surveillance. (Roitt, I., Brostoff, J. and Kale, D., Immunology, 17.1-17.12 (3rd ed., Mosby, St. Louis, Mo., 1993))

Various stages of tumor development can be described generally as follows:

a) Tumor evolution commences when a cell within a normal population sustains a genetic mutation that expands its tendency to proliferate.

b) Such genetically altered cells and their offspring continue to appear normal, but they reproduce excessively and lead to a condition termed hyperplasia. The altered cells may also secrete signaling factors or other molecules that cause changes in their local cellular and extracellular environment, including without limitation, the response of the immune system to them. Such environmental effects may in turn affect the viability, proliferation, and further mutations of the altered cells. After some time (months or years) a very small fraction of these altered cells may sustain additional mutation with subsequent loss of control of cell growth and further potential effects on their environment.

c) The offspring of these cells not only proliferate excessively but also appear abnormal in shape and in orientation. The tissue is now said to exhibit a condition termed dysplasia. After some time, one or more additional mutations may further alter cell behavior and the effect of the cells on their environment.

d) The influenced and genetically altered cells turn still more abnormal in growth and appearance. If the tumor mass does not invade through any boundaries between tissues, it is termed an in situ tumor. This tumor may stay contained indefinitely, however, some cells may acquire still more mutations.

e) A malignant or invasive tumor results if the genetic changes allow the tumor mass to initiate invading underlying tissue and to cast off cells into the blood or lymph. The defector cells may install new tumors loci (metastases) throughout the body.

Metastases represent the end products of a multistep cell-biological process termed the invasion-metastasis cascade, which involves dissemination of cancer cells to anatomically distant organ sites and their subsequent adaptation to foreign tissue microenvironments. Each of these events is driven by the acquisition of genetic and/or epigenetic alterations within tumor cells and the co-option of non-neoplastic stromal cells, which together endow incipient metastatic cells with traits needed to generate macroscopic metastases. (Volastyan, S., et al., Cell, 2011, vol. 147, 275-292)

An enormous variety of cancers affect different tissues throughout the body, which are described in detail in the medical literature. Over 85% of human cancers are solid tumors, including carcinomas, sarcomas and lymphomas. Different types of solid tumors are named for the type of cells that form them. Examples include cancer of the lung, colon, rectum, pancreatic, prostate, breast, brain, and intestine. Other human tumors derive from cells involved in the formation of immune cells and other blood cells, including leukemias and myelomas.

The incidence of cancer continues to climb as the general population ages, as new cancers develop, and as susceptible populations grow. A tremendous demand therefore exists for new methods and compositions that can be used to treat subjects with cancer.

Methods of Treating Cancer

Current cancer therapy may involve surgery, chemotherapy, hormonal therapy, biological therapy, targeted therapy, immunotherapy and/or radiation treatment to eradicate neoplastic cells in a patient (see, e.g., Stockdale, 1998, Medicine, vol. 3, Rubenstein and Federman, eds., Chapter 12, Section IV; and Baudino T A “Targeted Cancer Therapy: The Next Generation of Cancer Treatment”, Curr Drug Discov Technol. 2015; 12(1):3-20).

Such therapies may be used independently or in combinations. Choices of therapy will depend on the history and nature of the cancer, the condition of the patient, and, under the circumstances, the anticipated efficacy and adverse effects of the therapeutic agents and methods considered.

With respect to chemotherapy, there are a variety of chemotherapeutic agents and methods of delivery of such agents available for the treatment of different cancers. Most first generation chemotherapeutic agents were not tumor specific, have broad systemic effects, are toxic, and may cause significant and often dangerous side effects, including severe nausea, bone marrow depression, and immunosuppression.

Additionally, even with administration of combinations of chemotherapeutic agents, many tumor cells are or become resistant to chemotherapeutic agents. In fact, cells resistant to the particular chemotherapeutic agents used in a treatment protocol often prove to be resistant to other drugs, even if those agents act by different mechanism from those of the drugs used in the specific treatment. This phenomenon is referred to as multidrug resistance. Because of drug resistance, many cancers prove refractory to standard chemotherapeutic treatment protocols.

Thus, there exists a significant need for alternative compounds, compositions and methods for treating, preventing and managing cancer.

Further, whereas surgical resection and adjuvant therapy can cure well-confined primary tumors, metastatic disease is largely incurable because of its systemic nature and the resistance of disseminated tumor cells to existing therapeutic agents. This explains why greater than 90% of mortality from cancer is attributable to metastases, not the primary tumors from which these malignant lesions arise.

Pathobiology of Inflammatory Disease

Inflammation is a complex protective biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants, involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out necrotic cells and tissues damaged from the original insult and the inflammatory process, and to initiate tissue repair. (Ferrero-Miliani L, Nielsen O H, Andersen P S, Girardin S E; Nielsen; Andersen; Girardin (February 2007) Clin. Exp. Immunol. 147)

Inflammation is classified as either acute or chronic. Acute inflammation is the initial response of the body to harmful stimuli and is achieved by the increased movement of plasma and leukocytes (especially granulocytes) from the blood into the injured tissues. A series of biochemical events propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue.

Prolonged inflammation, known as chronic inflammation, is characterized by simultaneous destruction and healing of the tissue from the inflammatory process. It leads to a progressive shift in the type of cells present at the site of inflammation, such as mononuclear cells, and increases in systemic concentrations of cytokines such as TNF-α, IL-6, and CRP. (Petersen, A. M.; Pedersen, B. K. (2005). J Appl Physiol. 98 (4): 1154-1162)

Many proteins are involved in inflammation. Any of them are susceptible to genetic mutation which may impair or otherwise dysregulate their normal function and expression.

Methods of Treating Inflammatory Disease

Both small molecules and biologics are used to treat inflammatory diseases. Most treatments, however, are largely palliative.

A clear unmet medical need remains to find treatments that can mechanistically reduce chronic inflammatory diseases.

Pathobiology of Fibrotic Disease

Fibrosis, or the accumulation of extracellular matrix molecules that constitute scar tissue, is a common result of tissue injury. Pulmonary fibrosis, renal fibrosis, and hepatic cirrhosis are among the common fibrotic diseases which altogether represent a large unmet medical need. (Friedman S L, Sheppard D, Duffield J S, Violette S. Sci Transl Med January 9; 5(167)

Mechanisms of fibrogenesis include inflammatory as well as other pathways and generally involve reorganization of the actin cytoskeleton of affected cells, including epithelial cells, fibroblasts, endothelial cells, and macrophages.

Actin filament assembly and actomyosin contraction are directed by the Rho-associated coiled-coil forming protein kinase (ROCK) family of serine/threonine kinases (ROCK1 and ROCK2) and thus Rho is associated with fibrogenesis.

Tissue fibrosis is a leading cause of morbidity and mortality. 45% of deaths in the United States are attributable to fibrotic disorders. (Wynn T A. “Fibrotic Disease and the TH1/TH2 Paradigm.” Nat Rev Immunol 2004 August: 4(8): 583-594.) Treatments are generally palliative.

Idiopathic pulmonary fibrosis (IPF) is characterized by progressive lung scarring, short median survival, and limited therapeutic options, creating great need for new pharmacologic therapies. It is thought to result from repetitive environmental injury to the lung epithelium.

Targeted Therapy of Cancer, Inflammatory, and Fibrotic Diseases

Targeted therapies are a cornerstone of what is also referred to as precision medicine, a form of medicine that uses information about a person's genes and proteins to prevent, diagnose, and treat disease. Such therapeutics are sometimes called “molecularly targeted drugs,” “molecularly targeted therapies,” or similar names. The process of discovering them is often referred to as “rational drug design.”

A series of actions among molecules in a cell that leads to a certain end point or cell function is referred to as a molecular pathway.

Molecularly targeted drugs interact with a particular target molecule, or structurally related set of target molecules, in a pathway; thus modulating the endpoint effect of that pathway, such as a disease-related process; and, thus, yielding a therapeutic benefit.

Molecularly targeted drugs may be small molecules or biologics, usually antibodies. They may be useful alone or in combinations with other therapeutic agents and methods.

Because they target a particular molecule, or related set of molecules, and are usually designed to minimize their interactions with other molecules, targeted therapeutics may have fewer adverse side effects.

Targeted cancer drugs block the growth and spread of cancer by interacting with specific molecules or sets of structurally related molecules (altogether, “molecular targets”) that are involved, broadly speaking, in the growth, progression, lack of suppression or elimination, or spread of cancer. Such molecular targets may include proteins or genes involved in one or more cellular functions including, for example and without limitation, signal transduction, gene expression modulation, apoptosis induction or suppression, angiogenesis inhibition, or immune system modulation.

In some cases, the development of targeted cancer therapeutics involves identifying genes or proteins that are present in cancer cells but not normal cells or that are more abundant or more highly stimulated in cancer cells, especially if they are known to be involved in cancer processes, and then discovering agents that will interact with those targets and be associated with a desired therapeutic effect.

Targeted cancer therapies generally differ from standard cancer chemotherapy in several ways:

-   -   a. Targeted therapies are deliberately chosen or designed to         interact with their target(s), whereas many standard         chemotherapies were identified because they were found in         general to kill cells.     -   b. Targeted therapies are intended to act on specific molecular         targets that are associated with cancer, whereas most standard         chemotherapies act on all rapidly dividing normal and cancerous         cells. They may, however, also have known and sometime unknown         interactions with other molecules, so-called off-target effects.     -   c. Most targeted therapies are cytostatic (that is, they block         tumor cell proliferation), whereas standard chemotherapy agents         are usually cytotoxic (that is, they kill tumor cells). However,         some targeted therapies such as Antibody Drug Conjugates are         cytotoxic.

Targeted therapy monoclonal antibodies (mAbs) and targeted small molecules are being used as treatments for inflammatory diseases (Kotsovilis S, Andreakos E., Methods Mol Biol. 2014; 1060:37-59). They are used either as a monotherapy or in combination with other conventional therapeutic modalities, particularly if the disease under treatment is refractory to therapy using solely conventional techniques.

Some treatments for fibrotic disorders, such as idiopathic pulmonary fibrosis, hepatic fibrosis, and systemic sclerosis, target inflammatory pathways.

The Ras GTPase Family

The Ras superfamily of proteins are small GTPases with substantial amino acid sequence homology that act as signal transducers between cell surface receptors and several intracellular signaling cascades. These molecules are involved in the regulation of such essential cellular functions as cell survival, proliferation, motility, and cytoskeletal organization (see Karnoub et al., Nat. Rev. Mol. Cell Biol., 9: 517-531 (2008)).

Research has defined a number of subfamilies of the Ras superfamily, based largely on amino acid sequence homologies. These subfamilies are often referred to in an abbreviated manner based on the most commonly studied member of the class.

The GTP binding domains of one subfamily of the Ras superfamily having substantial sequence homology is commonly referred to as the Ras family or Ras.

There are four isoforms of Ras proteins, expressed from three different genes: H-Ras (Harvey sarcoma viral oncogene), N-Ras (neuroblastoma oncogene), and the splice variants K-Ras4A and K-Ras4B (Kirsten sarcoma viral oncogene) (see Karnoub et al., supra).

The GTP binding domains of another subfamily of the Ras superfamily having substantial sequence homology, is commonly referred to as the Rho family and includes proteins and groups of proteins referred to as Rho, Rac and Cdc42.

Ras Function and Pathways

All Ras isoforms share sequence identity in all of the regions that are responsible for GDP/GTP binding, GTPase activity, and effector interactions, suggesting a functional redundancy. However, studies clearly demonstrate that each Ras isoform functions in a unique, different way from the other Ras proteins in normal physiological processes as well as in pathogenesis (Quinlan et al., Future Oncol., 5: 105-116 (2009)).

Ras proteins cycle between ‘on’ and ‘off’ conformations that are conferred by the binding of GTP and GDP, respectively. Under physiological conditions, the transition between these two states is regulated by guanine nucleotide exchange factors (GEFs), which promote the activation of Ras proteins by stimulating the exchange of GDP for GTP exchange, and by GTPase-activating proteins (GAPs), which accelerate Ras-mediated GTP hydrolysis to GDP.

Several cell surface receptors activate Ras, such as Receptor Tyrosine Kinases (RTKs), growth factor receptors, cytokine receptors and integrins.

Once activated, Ras initiates signaling of the “MAPK pathway” (also referred to as the Ras-RAF-MEK-MAPK/ERK pathway) that affects cell growth, differentiation, proliferation, apoptosis and migration. It is also associated with other molecular pathways including phosphoinositide 3-kinases (PI3Ks), Rac1 GEF, and the Ra1-guanine nucleotide dissociation stimulator (GDS).

The MAPK pathway operates through a sequence of interactions among kinases. Activated by Ras in the “on”, GTP bound, state, a MAPK kinase kinase (MAPK3), such as Raf, MLK, or TAK, phosphorylates and activates a MAPK kinase, such as MEK, which then phosphorylates and increases the activity of one or more MAPKs, such as ERK1/2. PI3K is part of the PI3K/AKT/mTOR pathway regulating intracellular signaling important for several cellular functions such as survival, anti-apoptotic and cell cycle.

Ras Dysfunction is Causally Associated with Important Diseases and Disease Processes

Ras and its downstream pathways, including MAPK, have been studied extensively. They are causally associated with a range of diseases, including certain cancers, inflammatory disorders, Ras-associated autoimmune leukoproliferative disorder, and certain Rasopathies.

There is more than one distinct route to aberrant Ras activation including mutational activation of Ras itself, excessive activation of the wild-type protein through upstream signaling, and loss of a GAP function that is required to terminate activity of the protein.

One million deaths per year are attributed in the literature to mutations in K-Ras alone. (Frank McCormick. “K-Ras protein as a drug target.” Journal of Molecular Medicine (Berlin) 2016: 94: 253-258)

Ras is well documented in the literature as an oncogene. Ras oncogenes can initiate cancer in model organisms. Microinjection studies with antibodies that block Ras activity or block specific mutant alleles of Ras; ablation of K-Ras in mouse models of lung adenocarcinoma or pancreas cancer; and ablation of H-Ras all lead to tumor regression in mouse models.

About 30% (Prior I A, Lewis P D, Mattos C. Cancer Res. 2012 May 15; 72(10):2457-67) of human cancers have a mutated Ras protein with the most frequent mutations in residues G12, G13 and Q61. These oncogenic mutations result in impaired GTP hydrolysis and accumulation of Ras in the GTP-bound state leading to increased activation of Ras-dependent downstream effector pathways.

Table 1 summarizes recent data concerning the frequency of K-Ras and N-Ras mutations in an illustrative, but not exhaustive list, of human malignancies.

TABLE 1 Mutation Tumor Type Frequency K-Ras Pancreas 71% K-Ras Colon 35% K-Ras Small intestine 35% K-Ras Biliary tract 28% K-Ras Endometrium 22% K-Ras Lung 20% N-Ras Skin (melanoma) 20% K-Ras Cervix 19% K-Ras Urinary tract 16% Stephen AG, Esposito D, Bagni RK, McCormick F. Cancer Cell. 2014 Mar. 17; 25(3):272-81.

Ras mutants, and in some cases Ras over-activation, are associated in the literature with a wide range of significant cancer associated processes including: cell proliferation, DNA checkpoint integrity, replicative stress related clonal selection, suppression of apoptosis, metabolic reprogramming, autophagy, microenvironment remodeling, immune response evasion, and metastatic processes. The detailed mechanisms, interdependencies, and frequency of these effects across different tumor types and stages of cancer development remain to be elucidated comprehensively.

Proliferative effects associated in the literature with oncogenic Ras include transcriptional upregulation of growth factors; upregulation of growth factor receptor expression; upregulation of integrins that promote proliferation and downregulation of those associated with cellular quiescence; upregulation of transcription factors required for cell cycle entry; acceleration through cell cycle transitions; downregulation of anti-proliferative TGFβ signaling; and the suppression of cyclin-dependent kinase inhibitors.

MAPK signaling has been shown to enhance programmed death-ligand 1 (PD-L1) expression in KRas mutant lung cancer cells and thus Ras mutations are associated with the suppression of immune responses to cancer. (Sumimoto et al., PLOS One 2016 November 15; DOI:10.1371/journal.pone.0166626) Anti-PD-1 and anti-PD-L1 monoclonal antibodies have demonstrated clinical activity against tumors including non-small cell lung cancers.

Ras is also implicated through the MAPK pathways as a cause of a range of pathological inflammatory conditions. In addition to ERK1/2, the MAPKs ERK5, c-Jun N-terminal kinases (JNKs) and p38 isoforms have been shown to be implicated in inflammatory response. (Huang, et al. 2010, Protein Cell, 1(3), 218-226)

Ras is causally associated with inflammatory diseases including the following: rheumatoid arthritis (Abreu J R, de Launay D, Sanders M E, Grabiec A M, Sande van de M G, Tak P P, Reedquist K A: The Ras guanine nucleotide exchange factor RasGRF1 promotes matrix metalloproteinase-3 production in rheumatoid arthritis synovial tissue. Arthritis Res Ther. 2009, 11: R121-10.1186/ar2785), which is the most common cause of disability (Hootman J M, Brault M W, Helmick C G, Theis K A, Armour B S. Prevalence and most common causes of disability among adults—United States 2005, MMWR, 2009, 58(16):421-6); atherosclerosis (Fonarow G (2003), Cleve. Clin. J. Med. 70: 431-434); inflammatory bowel disease (IBD), such as Crohn's disease (Ignacio C S, Sandvik A K, Bruland T, Andreu-Ballester J C, J. Crohns Colitis, 2017 Mar. 16. doi: 10); ulcerative colitis, spondyloarthropathies, idiopathic pulmonary fibrosis, juvenile arthritis, psoriasis, psoriatic arthritis, and others.

Ras has been causally associated with Ras-associated autoimmune leukoproliferative disorder, a nonmalignant clinical syndrome initially identified in a subset of putative autoimmune lymphoproliferative syndrome (ALPS) patients. (Katherin Calvo, et al. “JMML and RALD (Ras-associated autoimmune leukoproliferative disorder): common genetic etiology yet clinically distinct entities” Blood, 2015 Apr. 30; 125(18): 2753-2758)

Aberrant Ras signaling is causally implicated in the family of Rasopathies including neurofibromatosis type 1, Noonan's syndrome, and Costello syndrome.

Ras as a Therapeutic Molecular Target

Interference with Ras superfamily member signaling in cell based and animal models of the aforementioned diseases modulates disease processes.

Ras superfamily proteins, and particularly Ras and downstream pathway elements, have thus long been discussed as theoretical molecular targets for the development of targeted therapeutics. In theory, a molecule could serve as a therapeutic agent in diseases associated with aberrant Ras signaling if it could disrupt such Ras signaling.

In theory, it was recognized that a mechanism for downregulating aberrant Ras signaling could be to interfere with one or more steps in the Ras signaling process involving GTP binding in a manner that left the GTP in other than an “on” configuration. However, while this was a concept in theory, based on two widely accepted findings, it has also long been accepted by the scientific community that it would not be possible to achieve.

GTP and GDP had been found to bind to the GTP binding domain of Ras with single to double digit picomolar affinities.

The cellular concentration of GTP had been found to be substantially in excess of this range.

The widely accepted findings concerning the single to double digit picomolar range of affinities of GTP and GDP for the Ras GTP binding domain were determined by kinetic and filter binding measurements between Ras and radiolabeled GDP and GTP (Feuerstein J, Kalbitzer H R, John J, Goody R S, Wittinghofer A. Eur. J. Biochem., 1987 Jan. 2, 162(1):49-55; and John J, Sohmen R, Feuerstein J, Linke R, Wittinghofer A, Goody R S. Biochemistry, 1990 Jun. 26, 29(25):6058-65).

Consistent with these findings, and often citing them, the GTP binding domain of Ras has widely been accepted and reported in preeminent journal editorials, reviews, and research papers to be “undruggable.” (Papke B, Der C J., Science, 2017 Mar. 17, 355(6330):1158-1163; Stephen A G, Esposito D, Bagni R K, McCormick F, Cancer Cell, 2014 Mar. 17, 25(3):272-81; and Ostrem J M, Shokat K M, Nat. Rev. Drug Discov., 2016 November, 15(11):771-785)

Accordingly, research concerning targeted Ras therapeutics has focused on domains of the Ras protein other than the GTP binding site. These include, for example, farnesyltransferase inhibitors (FTIs) that prevent Ras attachment to the inner side of the plasma membrane, and molecules that compete with the interaction of Ras with the exchange factor SOS or downstream effectors.

Thus, it has been thought that a molecule could not be developed to compete with GTP binding to the GTP binding domain of Ras. Compounds that do so, however, would fill a need in the field.

The Rho Family Function and Pathways

The Rho subfamily of the Ras superfamily currently includes approximately 22 proteins most of which scientists commonly divide into subgroups including those referred to as Cdc42, Rac, and Rho. (Boureux A, Vignal E, Faure S, Fort P (2007). “Evolution of the Rho family of ras-like GTPases in eukaryotes”. Mol Biol Evol 24 (1): 203-16).

The three most commonly studied members of the Rho subfamily have been Cdc42, Rac1, and RhoA.

The Cdc42 group includes Cdc42, TC10, TCL, Chip, and Wrch-1.

The Rac group includes Rac1, Rac2, Rac3, and RhoG.

The RhoA group includes RhoA, RhoB, and RhoC.

Other Rho subfamily GTPases not included in the Cdc42. Rac, or Rho groups include RhoE/Rnd3, RhoH/TTF, Rif, RhoBTB1, RhoBTB2, Miro-1, Miro-2, RhoD, Rnd1, and Rnd2.

Like other Ras superfamily proteins, the Rho subfamily GTPases cycle between ‘on’ and ‘off’ conformations that are conferred by the binding of GTP and GDP, respectively. Under physiological conditions, the transition between these two states is regulated by guanine nucleotide exchange factors (GEFs), which promote the activation of Rho subfamily proteins by stimulating the release of GDP and the binding of GTP, and by GTPase-activating proteins (GAPs), which accelerate Rho subfamily member-mediated GTP hydrolysis to GDP. Guanine nucleotide dissociation inhibitors (GDIs) proteins form a large complex with the Rho protein, helping to prevent diffusion within the membrane and into the cytosol and thus acting as an anchor and allowing tight spatial control of Rho activation.

The Rho subfamily members are intracellular proteins that affect a large number of downstream pathways broadly involving cytoskeleton organization, cell polarity, migration, transcription and proliferation, and, more particularly, membrane and vesicular trafficking, cell cycling, microtubule stability, actin membrane linkages, actin polymerization, myosin phosphorylation, API dependent gene expression, cell adhesion, cell contractility, cell adhesion, and MTOC orientation. (Martin Schwartz. “Rho Signalling at a Glance.” Journal of Cell Science. 2004: (117: pp. 5457-5458). and (Bustelo X R, Sauzeau V, Berenjeno I M (2007). “GTP-binding proteins of the Rho/Rac family: regulation, effectors and functions in vivo” BioEssays. 29 (4): 356-370).

Rho Family Dysfunction is Causally Associated with Important Diseases

Rho subfamily GTPases have been reported to contribute to most steps of cancer initiation and progression including the acquisition of unlimited proliferation potential, survival and evasion from apoptosis, angiogenesis, tissue invasion, motility, and the establishment of metastases. (Matteo Parri and Paolo Chiarugi. “Rac and Rho GTPases in Cancer Cell Motility Control.” Cell Communication and Signalling. 2010(8:23))

High Rho subfamily protein levels are frequently associated with human tumors. High RhoA levels have been associated with human liver, skin, colon, ovarian, bladder, gastric, esophageal squamous cell, testicular, and breast cancer. High Rho B, C, or H levels have been associated with breast, squamous cell, pancreatic, breast, liver, ovarian, head and neck, prostate, non-small cell lung, and gastric cancers and melanoma metastase. High Rac1 levels have been associated with human testicular, gastric, breast, and squamous cell cancers. High Rac2 or Rac3 have been associated with breast colon, head and neck, and squamous cell cancers. (Matteo Parri and Paolo Chiarugi. “Rac and Rho GTPases in Cancer Cell Motility Control.” Cell Communication and Signalling. 2010(8:23). Gain-of-function mutations such as P29S of Rac1 were detected in melanoma, breast, head and neck cancers (Alan J K, Lundquist E A. Mutationally activated Rho GTPases in cancer. Small GTPases. 2013 July-September; 4(3):159-63)

Unlike Ras proteins, which are frequently mutated in cancer (around 30%), Rho subfamily proteins themselves are generally not found to be mutated in cancer. Rather, aberrant activity of Rho subfamily proteins in cancer appears to occur by overexpression of these proteins or by aberrant regulation of molecules that control their activity, such as activation or overexpression of GEFs and inactivation or loss of GAPs or GDIs (Alan J K, Lundquist E A. Mutationally activated Rho GTPases in cancer. Small GTPases. 2013 July-September; 4(3):159-63).

Interactions between Rac and Rho proteins are believed to modulate certain forms of mesenchymal and amoeboid cell movement associated with cancer.

Rho subfamily associated kinases (ROCK1 and ROCK2) are implicated as mediators of multiple profibrotic processes including those associated with idiopathic pulmonary fibrosis. (Knipe R S, Tager E M, and Liao J K. “The Rho kinases: critical mediators of multiple profibrotic processes and rational targets for new therapies for pulmonary fibrosis.” Pharmacol Rev. 2015 67(1):103-17.)

3. SUMMARY

For the first time, the affinity of GTP for the GTP binding domain of K-Ras utilizing a Scintillation Proximity Assay (SPA) and MicroScale Thermophoresis (MST) has been measured and disclosed herein. These methods were not available when Wittinghofer and colleagues (referenced above) undertook their studies.

In SPA and MST studies, it was found and is disclosed herein that the affinity of GTP for the K-Ras GTP binding domain across wild type and mutant K-Ras is in the range of 100-465 nanomolar. This therefore led to the novel, unanticipated conclusion that compounds such as small molecules could be discovered that would bind to a Ras GTP binding domain and compete with the binding of GTP to Ras.

Provided herein is a novel cell-free assay for the identification of small molecules that bind to the GTP binding domain and compete with GTP binding to, for example, wild-type KRas, KRas G12D mutant, KRas G12C mutant, KRas Q61H mutant, KRas G12D/Q61H double mutant, KRas G12C/Q61H double mutant, Rac1 and RhoA proteins.

Utilizing this assay as a screening and analytical tool, over 1000 small molecules are provided that bind competitively with GTP to a Ras GTP binding domain, thereby confirming the significance of the novel and unanticipated binding affinity findings. Provided herein is a method of testing the affinity of a compound for a Ras GTP binding domain comprising the novel assay.

Utilizing this assay, it was also demonstrated that over 1000 small molecules provided herein also bind competitively with GTP to both Rac and Rho GTPase binding domains. Provided herein is a method of testing the affinity of a compound for Rac and Rho GTP binding domains comprising the novel assay.

It is also demonstrated herein in cell-based assays that certain of these molecules inhibit activation of the MAPK pathway and downregulate the proliferation of different human tumors.

It is further demonstrated herein in cell-based assays that certain of these molecules downregulate the excretion of inflammatory cytokines.

It has also been discovered and disclosed herein that certain amino acids in the Ras GTP binding domain enable the heretofore unanticipated competitive binding to that domain between compounds, such as small molecules, and GTP.

5.2. Ras GTP Binding Domain

Data Concerning the Affinity of GTP to the Ras GTP Binding Domain

For the first time, the affinity of GTP for the GTP binding domain of K-Ras utilizing a Scintillation Proximity Assay (SPA) and MicroScale Thermophoresis (MST) has been measured and disclosed herein. These methods were not available when Wittinghofer and colleagues undertook their studies.

In SPA and MST studies, it was found and is disclosed herein that the affinity of GTP for the K-Ras GTP binding domain across wild type and mutant K-Ras is in the range of 100-465 nanomolar (see results in Table 2). This therefore led to the novel, unanticipated conclusion that compounds such as small molecules could be discovered that would bind to a Ras GTP binding domain and compete with the binding of GTP to Ras. SPA and MST studies performed on the Rac-1 and Rho-A members of the Rho subfamily show that the affinity of GTP for the binding domain of these Rho subfamily members is in the range of 120-170 nanomolar (see results in Table 2).

TABLE 2 MST and SPA Results for GTP Affinity for K-Ras and Rho Subfamily Binding Domains Protein MST SPA K-Ras (wild type) 463 ± 2 nM 243 ± 15 nM K-Ras (G12D) 244 ± 12 nM 270 ± 15 nM K-Ras (G12C) 207 ± 46 nM 258 ± 18 nM K-Ras (Q61H) 157 ± 21 nM 118 ± 11 nM K-Ras (Q61H/G12D) 268 ± 108 nM 135 ± 19 nM K-Ras (Q61H/G12C) 266 ± 57 nM 104 ± 11 nM Rac-1 166 ± 10 nM 151 ± 14 nM Rho-A 130 ± 5 nM 129 ± 12 nM

The Discovery of Small Molecules that Bind to a Ras GTP Binding Domain in Competition with GTP

Provided herein is an assay for the identification of small molecules that bind to a Ras GTP binding domain in competition with GTP.

The useful and novel approach for drug discovery described herein is to identify small molecule inhibitors that will compete and block interactions between GTP and GTP-binding proteins. By interacting with the GDP/GTP-binding site of GTP-binding proteins small molecules so identified may induce a GDP-bound or other inactive conformation of the GTP-binding proteins and thus block signal transduction pathways downstream of the GTP-binding protein.

The assay developed measures and quantifies the ability of tested small molecules in a cell-free system to compete with GTP or GDP binding. The assay can be used in low volumes or for High Throughput Screening (HTS) to screen a compound library and to support medicinal chemistry Structure Activity Relationship (SAR) efforts.

This is a competitive binding assay. It involves the immobilization of a protein on solid phase, interaction with a small molecule drug candidate, and then competitive binding with a labeled native GTP or GDP ligand.

In one embodiment, provided herein is a method of testing the ability of one or more compounds to bind to the GTP binding domain and to compete for GTP binding of one or more members of the Ras superfamily comprising:

a) expressing a Ras superfamily protein or mutant thereof as a tagged protein;

b) contacting the one or more compounds to the tagged protein, followed by incubating the combination;

c) adding labeled-GTP or labeled-GDP to each protein-compound combination, followed by incubating the resulting mixture; and

d) measuring the amount of bound labeled-GTP or bound labeled-GDP.

In one embodiment, the method further comprises between step a) and step b): adding the tagged protein to one or more wells of a ligand coated single or multi-well plate and incubating the tagged protein.

In one embodiment of the method, one or more members of the Ras superfamily is Ras. In one embodiment of the method, the Ras is DIRAS1; DIRAS2; DIRAS3; ERAS; GEM; HRAS; KRAS; MRAS; NKIRAS1; NKIRAS2; NRAS; RALA; RALB; RAP1A; RAP1B; RAP2A; RAP2B; RAP2C; RASD1; RASD2; RASL10A; RASL10B; RASL11A; RASL11B; RASL12; REM1; REM2; RERG; RERGL; RRAD; RRAS; or RRAS2. In one embodiment of the method, the Ras is HRAS, KRAS, NRAS, or a mutant thereof. In one embodiment of the method, the Ras is HRAS or a mutant thereof. In one embodiment of the method, the Ras is KRAS or a mutant thereof. In one embodiment of the method, the Ras is NRAS or a mutant thereof.

In one embodiment of the method, the Ras superfamily protein is KRas G12D mutant protein. In one embodiment of the method, the Ras superfamily protein is KRas G12C mutant protein. In one embodiment of the method, the Ras superfamily protein is KRas wild type protein. In one embodiment of the method, the Ras superfamily protein is KRas Q61H mutant protein. In one embodiment of the method, the Ras superfamily protein is KRas G12D/Q61H double mutant protein. In one embodiment of the method, the Ras superfamily protein is G12C/Q61H double mutant.

In one embodiment of the method, one or more members of the Ras superfamily is Rho. In one embodiment of the method, the Rho is RHOA; RHOB; RHOBTB1; RHOBTB2; RHOBTB3; RHOC; RHOD; RHOF; RHOG; RHOH; RHOJ; RHOQ; RHOU; RHOV; RND1; RND2; RND3; RAC1; RAC2; RAC3; CDC42, or a mutant thereof. In one embodiment of the method, the Ras superfamily protein is Rho-A protein.

In one embodiment of the method, one or more members of the Ras superfamily is Rac. In one embodiment of the method, the Rho is Rac or a mutant thereof. In one embodiment of the method, the Rac is RAC1; RAC2; RAC3; RHOG, or a mutant thereof. In one embodiment of the method, the Ras superfamily protein is Rac-1 protein.

In one embodiment of the method, the tagged protein is tagged with His. In one embodiment of the method, the ligand is nickel. In one embodiment of the method, the labeled-GTP is Cy3-GTP or Cy5-GTP. In one embodiment of the method, the buffer is Buffer-I which comprises 50 mM Tris (pH 7.5), 150 mM NaCl, 1 mM MgCl₂, and 1 mM DTT. In another embodiment of the method, the buffer is Buffer-I which comprises 50 mM Tris (pH 7.5), 1 mM MgCl₂, and 1 mM DTT.

The form of the assay involves the binding of His-tagged protein to nickel coated plates and a native form of GTP covalently labeled with Cy3 or Cy5 fluorescent probes.

In theory, the assay is suitable for use with any GTP or GDP binding protein. The Examples demonstrate that the assay can be utilized for Ras and Ras mutants, Rac-1 and Rho-A human proteins expressed and purified as recombinant proteins.

Different tag/ligand combinations can be used in the assay. The protein may be expressed as a fusion protein with a tag such as His, HA, Flag or GST; or, the protein can be labeled by a tag such as biotin via chemical reaction. The counter molecule (ligand or binder) interacting with the tag will bind or coat the solid phase. The solid phase could be a plate (96, 384 or 1536 wells plate) and column beads such as sepharose, agarose and cellulose. Binders could include nickel, antibodies, glutathione and streptavidin. Examples of tag:ligand combinations include His (polyhistidine, at least 6 histidines):nickel, GST (Glutathione-S-transferase):glutathione, HA (amino acids 98-106 of human influenza hemagglutinin):anti-HA antibodies, Fc (constant region of human IgG):protein A, FLAG (the peptide DYDDDDK):Antibodies (M1. M2, 4E11), Myc (the peptide EQKLISEED derived the myc protein): Anti-myc antibodies, and biotin: streptavidin (or avidin).

Heretofore, attempts to measure small molecule competitors for GTP protein interactions have relied on the ability of the tested small molecules to prevent binding of labeled GTP to the GTP-binding protein. A novel component of this assay is the use of the highly sensitive Cy3 or Cy5 probes. Similar probes which might be used include other high sensitivity fluorophores that can be detected at concentrations below 1 micromolar in solution, and radioactive labeling. The inventors are not aware of any publication suggesting the adaptation of the probes we have used, or similar probes, for use in a competitive binding assay.

Combination Therapy with a Second Active Agent

The compound provided herein, or a derivative thereof, can also be combined or used in combination with other therapeutic agents useful in the treatment and/or prevention of cancer described herein.

In one embodiment, provided herein is a method of treating, preventing, or managing cancer, comprising administering to a subject a compound provided herein, or a derivative thereof; in combination with one or more second active agents, and optionally in combination with radiation therapy, blood transfusions, or surgery. Examples of second active agents are disclosed herein.

As used herein, the term “in combination” includes the use of more than one therapy (e.g., one or more prophylactic and/or therapeutic agents). However, the use of the term “in combination” does not restrict the order in which therapies (e.g., prophylactic and/or therapeutic agents) are administered to a subject with a disease or disorder. A first therapy (e.g., a prophylactic or therapeutic agent such as a compound provided herein, a compound provided herein, e.g., the compound provided herein, or a derivative thereof) can be administered prior to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks before), concomitantly with, or subsequent to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks after) the administration of a second therapy (e.g., a prophylactic or therapeutic agent) to the subject. Triple therapy is also contemplated herein.

Administration of the compound provided herein, or a derivative thereof and one or more second active agents to a subject can occur simultaneously or sequentially by the same or different routes of administration. The suitability of a particular route of administration employed for a particular active agent will depend on the active agent itself (e.g., whether it can be administered orally without decomposing prior to entering the blood stream) and the cancer being treated.

The route of administration of the compound provided herein, or a derivative thereof, is independent of the route of administration of a second therapy. In one embodiment, the compound provided herein, or a derivative thereof, is administered orally. In another embodiment, the compound provided herein, or a derivative thereof, is administered intravenously. Thus, in accordance with these embodiments, the compound provided herein, or a derivative thereof, is administered orally or intravenously, and the second therapy can be administered orally, parenterally, intraperitoneally, intravenously, intraarterially, transdermally, sublingually, intramuscularly, rectally, transbuccally, intranasally, liposomally, via inhalation, vaginally, intraoccularly, via local delivery by catheter or stent, subcutaneously, intraadiposally, intraarticularly, intrathecally, or in a slow release dosage form. In one embodiment, the compound provided herein, or a derivative thereof, and a second therapy are administered by the same mode of administration, orally or by IV. In another embodiment, the compound provided herein, or a derivative thereof, is administered by one mode of administration, e.g., by IV, whereas the second agent (an anticancer agent) is administered by another mode of administration, e.g., orally.

In one embodiment, the second active agent is administered intravenously or subcutaneously and once or twice daily in an amount of from about 1 to about 1000 mg, from about 5 to about 500 mg, from about 10 to about 350 mg, or from about 50 to about 200 mg. The specific amount of the second active agent will depend on the specific agent used, the type of disease being treated or managed, the severity and stage of disease, and the amount of the compound provided herein, or a derivative thereof, and any optional additional active agents concurrently administered to the subject.

One or more second active ingredients or agents can be used together with the compound provided herein, or a derivative thereof, in the methods and compositions provided herein. Second active agents can be large molecules (e.g., proteins) or small molecules (e.g., synthetic inorganic, organometallic, or organic molecules).

Examples of large molecule active agents include, but are not limited to, hematopoietic growth factors, cytokines, and monoclonal and polyclonal antibodies, particularly, therapeutic antibodies to cancer antigens. Typical large molecule active agents are biological molecules, such as naturally occurring or synthetic or recombinant proteins.

In one embodiment, the inflammatory disease is inflammation-associated cancer development. As disclosed here, the compounds provided herein are useful in treatment of cancer. It is well recognized that the immune inflammatory state serves as a key mediator of the middle stages of tumor development. It is also well known that chronic inflammation can predispose an individual to cancer. Chronic inflammation is caused by a variety of factors, including bacterial, viral, and parasitic infections. The longer the inflammation persists, the higher the risk of associated carcinogenesis. Anti-inflammatory cancer therapy prevents premalignant cells from turning fully cancerous or impedes existing tumors from spreading to distant sites in the body. Thus, in one embodiment, the compounds provided herein are useful in treating inflammatory cancers. Such cancers, and the chronic inflammatory conditions that predispose susceptible cells to neoplastic transformation, include gastric adenocarcinoma (gastritis), mucosa-associated lymphoid tissue (MALT) lymphoma (gastritis), bladder, liver and rectal carcinomas (schistosomiasis), cholangiocarcinoma and colon carcinoma (cholangitis), gall bladder cancer (chronic cholecystitis), ovarian and cervical carcinoma (pelvic inflammatory disease, chronic cervicitis), skin carcinoma (osteomyelitis), colorectal carcinoma (inflammatory bowel disease), esophageal carcinoma (reflux esophagitis, Barrett's esophagus), bladder cancer (bladder inflammation (cystitis)), mesothelioma and lung carcinoma (asbestosis, silicosis), oral squamous cell carcinoma (gingivitis, lichen planus), pancreatic carcinoma (pancreatitis, protease mutation), vulvar squamous cell carcinoma (lichen sclerosis), salivary gland carcinoma (slaladenitis), lung carcinoma (bronchitis) and MALT lymphoma (Sjogren syndrome, Hashimoto's thyroiditis).

To the stirred reaction mixture 0.5 mmol of Reagent A (in case of amine salt, an additional 1.5 equivalent amount of DIPEA was added to the reaction mixture), and 0.72 mmol of 2-chloro-N-methylpyridinium iodide was added. The reaction vial was placed into a water bath and left at 100° C. for 6 hrs. Reaction mixture was cooled to room temperature and diluted by 6 mL of water. Then the vial was sonicated. If crystalline precipitate was formed it was filtered off. In case an oily product was formed the vial was left overnight, then the water layer was removed and 2-propanol (1 mL) was added to cause the crystallization. The precipitate was filtered, washed twice with a sodium carbonate solution, and then washed with methanol.

6.6. Pharmaceutical Compositions

The pharmaceutical compositions provided herein contain therapeutically effective amounts of one or more of compounds provided herein and a pharmaceutically acceptable carrier, diluent or excipient.

The compounds can be formulated into suitable pharmaceutical preparations such as solutions, suspensions, tablets, dispersible tablets, pills, capsules, powders, sustained release formulations or elixirs, for oral administration or in sterile solutions or suspensions for ophthalmic or parenteral administration, as well as transdermal patch preparation and dry powder inhalers. Typically the compounds described above are formulated into pharmaceutical compositions using techniques and procedures well known in the art (see, e.g., Ansel Introduction to Pharmaceutical Dosage Forms, Seventh Edition 1999).

In the compositions, effective concentrations of one or more compounds or pharmaceutically acceptable salts is (are) mixed with a suitable pharmaceutical carrier or vehicle. In certain embodiments, the concentrations of the compounds in the compositions are effective for delivery of an amount, upon administration, that treats, prevents, or ameliorates one or more of the symptoms and/or progression of a disease or disorder disclosed herein.

Typically, the compositions are formulated for single dosage administration. To formulate a composition, the weight fraction of compound is dissolved, suspended, dispersed or otherwise mixed in a selected vehicle at an effective concentration such that the treated condition is relieved or ameliorated. Pharmaceutical carriers or vehicles suitable for administration of the compounds provided herein include any such carriers known to those skilled in the art to be suitable for the particular mode of administration.

In addition, the compounds may be formulated as the sole pharmaceutically active ingredient in the composition or may be combined with other active ingredients. Liposomal suspensions, including tissue-targeted liposomes, such as tumor-targeted liposomes, may also be suitable as pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art. For example, liposome formulations may be prepared as known in the art. Briefly, liposomes such as multilamellar vesicles (MLV's) may be formed by drying down egg phosphatidyl choline and brain phosphatidyl serine (7:3 molar ratio) on the inside of a flask. A solution of a compound provided herein in phosphate buffered saline lacking divalent cations (PBS) is added and the flask shaken until the lipid film is dispersed. The resulting vesicles are washed to remove unencapsulated compound, pelleted by centrifugation, and then resuspended in PBS.

The active compound is included in the pharmaceutically acceptable carrier in an amount sufficient to exert a therapeutically useful effect in the absence of undesirable side effects on the subject treated. The therapeutically effective concentration may be determined empirically by testing the compounds in in vitro and in vivo systems described herein and then extrapolated therefrom for dosages for humans. In some embodiments, the active compound is administered in a method to achieve a therapeutically effective concentration of the drug. In some embodiments, a companion diagnostic (see, e.g., Olsen D and Jorgensen J T, Front. Oncol., 2014 May 16, 4:105, doi: 10.3389/fonc.2014.00105) is used to determine the therapeutic concentration and safety profile of the active compound in specific subjects or subject populations.

The concentration of active compound in the pharmaceutical composition will depend on absorption, tissue distribution, inactivation and excretion rates of the active compound, the physicochemical characteristics of the compound, the dosage schedule, and amount administered as well as other factors known to those of skill in the art. For example, the amount that is delivered is sufficient to ameliorate one or more of the symptoms of a disease or disorder disclosed herein.

In certain embodiments, a therapeutically effective dosage should produce a serum concentration of active ingredient of from about 0.1 ng/mL to about 50-100 μg/mL. In one embodiment, the pharmaceutical compositions provide a dosage of from about 0.001 mg to about 2000 mg of compound per kilogram of body weight per day. Pharmaceutical dosage unit forms are prepared to provide from about 1 mg to about 1000 mg and in certain embodiments, from about 10 to about 500 mg of the essential active ingredient or a combination of essential ingredients per dosage unit form.

The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at intervals of time. It is understood that the precise dosage and duration of treatment is a function of the disease being treated and may be determined empirically using known testing protocols or by extrapolation from in vivo or in vitro test data. It is to be noted that concentrations and dosage values may also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed compositions.

Thus, effective concentrations or amounts of one or more of the compounds described herein or pharmaceutically acceptable salts thereof are mixed with a suitable pharmaceutical carrier or vehicle for systemic, topical or local administration to form pharmaceutical compositions. Compounds are included in an amount effective for ameliorating one or more symptoms of, or for treating, retarding progression, or preventing. The concentration of active compound in the composition will depend on absorption, tissue distribution, inactivation, excretion rates of the active compound, the dosage schedule, amount administered, particular formulation as well as other factors known to those of skill in the art.

The compositions are intended to be administered by a suitable route, including but not limited to oral, parenteral, subcutaneous, intravenous, intramuscular, intraperitoneal, intrathecal, mucosal, dermal, transdermal, buccal, rectal, topical, local, nasal or inhalation. For oral administration, capsules and tablets can be formulated. The compositions are in liquid, semi-liquid or solid form and are formulated in a manner suitable for each route of administration.

Solutions or suspensions used for parenteral, intradermal, subcutaneous, or topical application can include any of the following components: a sterile diluent, such as water for injection, saline solution, fixed oil, polyethylene glycol, glycerine, propylene glycol, dimethyl acetamide or other synthetic solvent; antimicrobial agents, such as benzyl alcohol and methyl parabens; antioxidants, such as ascorbic acid and sodium bisulfite; chelating agents, such as ethylenediaminetetraacetic acid (EDTA); buffers, such as acetates, citrates and phosphates; and agents for the adjustment of tonicity such as sodium chloride or dextrose. Parenteral preparations can be enclosed in ampules, pens, disposable syringes or single or multiple dose vials made of glass, plastic or other suitable material.

In instances in which the compounds exhibit insufficient solubility, methods for solubilizing compounds may be used. Such methods are known to those of skill in this art, and include, but are not limited to, using cosolvents, such as dimethylsulfoxide (DMSO), using surfactants, such as TWEEN®, or dissolution in aqueous sodium bicarbonate.

Upon mixing or addition of the compound(s), the resulting mixture may be a solution, suspension, emulsion or the like. The form of the resulting mixture depends upon a number of factors, including the intended mode of administration and the solubility of the compound in the selected carrier or vehicle. The effective concentration is sufficient for ameliorating the symptoms of the disease, disorder or condition treated and may be empirically determined.

The pharmaceutical compositions are provided for administration to humans and animals in unit dosage forms, such as tablets, capsules, pills, powders, granules, sterile parenteral solutions or suspensions, and oral solutions or suspensions, and oil water emulsions containing suitable quantities of the compounds or pharmaceutically acceptable salts thereof. The pharmaceutically therapeutically active compounds and salts thereof are formulated and administered in unit dosage forms or multiple dosage forms. Unit dose forms as used herein refer to physically discrete units suitable for human and animal subjects and packaged individually as is known in the art. Each unit dose contains a predetermined quantity of the therapeutically active compound sufficient to produce the desired therapeutic effect, in association with the required pharmaceutical carrier, vehicle or diluent. Examples of unit dose forms include ampules and syringes and individually packaged tablets or capsules. Unit dose forms may be administered in fractions or multiples thereof. A multiple dose form is a plurality of identical unit dosage forms packaged in a single container to be administered in segregated unit dose form. Examples of multiple dose forms include vials, bottles of tablets or capsules or bottles of pints or gallons. Hence, multiple dose form is a multiple of unit doses which are not segregated in packaging.

Sustained-release preparations can also be prepared. Suitable examples of sustained-release preparations include semipermeable matrices of solid hydrophobic polymers containing the compound provided herein, which matrices are in the form of shaped articles, e.g., films, or microcapsule. Examples of sustained-release matrices include iontophoresis patches, polyesters, hydrogels (for example, poly(2-hydroxyethyl-methacrylate), or poly(vinylalcohol)), polylactides, copolymers of L-glutamic acid and ethyl-L-glutamate, non-degradable ethylene-vinyl acetate, degradable lactic acid-glycolic acid copolymers such as the LUPRON DEPOT™ (injectable microspheres composed of lactic acid-glycolic acid copolymer and leuprolide acetate), and poly-D-(−)-3-hydroxybutyric acid. While polymers such as ethylene-vinyl acetate and lactic acid-glycolic acid enable release of molecules for over 100 days, certain hydrogels release proteins for shorter time periods. When encapsulated compound remain in the body for a long time, they may denature or aggregate as a result of exposure to moisture at 37° C., resulting in a loss of biological activity and possible changes in their structure. Rational strategies can be devised for stabilization depending on the mechanism of action involved. For example, if the aggregation mechanism is discovered to be intermolecular S—S bond formation through thio-disulfide interchange, stabilization may be achieved by modifying sulfhydryl residues, lyophilizing from acidic solutions, controlling moisture content, using appropriate additives, and developing specific polymer matrix compositions.

Dosage forms or compositions containing active ingredient in the range of 0.005% to 100% with the balance made up from non toxic carrier may be prepared. For oral administration, a pharmaceutically acceptable non toxic composition is formed by the incorporation of any of the normally employed excipients, such as, for example pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, talcum, cellulose derivatives, sodium crosscarmellose, glucose, sucrose, magnesium carbonate or sodium saccharin. Such compositions include solutions, suspensions, tablets, capsules, powders and sustained release formulations, such as, but not limited to, implants and microencapsulated delivery systems, and biodegradable, biocompatible polymers, such as collagen, ethylene vinyl acetate, polyanhydrides, polyglycolic acid, polyorthoesters, polylactic acid and others. Methods for preparation of these compositions are known to those skilled in the art. The contemplated compositions may contain about 0.001% 100% active ingredient, in certain embodiments, about 0.1 85% or about 75-95%.

The active compounds or pharmaceutically acceptable salts may be prepared with carriers that protect the compound against rapid elimination from the body, such as time release formulations or coatings.

The compositions may include other active compounds to obtain desired combinations of properties. The compounds provided herein, or pharmaceutically acceptable salts thereof as described herein, may also be advantageously administered for therapeutic or prophylactic purposes together with another pharmacological agent known in the general art to be of value in treating one or more of the diseases or medical conditions referred to hereinabove, such as diseases related to oxidative stress. It is to be understood that such combination therapy constitutes a further aspect of the compositions and methods of treatment provided herein.

Lactose-free compositions provided herein can contain excipients that are well known in the art and are listed, for example, in the U.S. Pharmocopia (USP) SP (XXI)/NF (XVI). In general, lactose-free compositions contain an active ingredient, a binder/filler, and a lubricant in pharmaceutically compatible and pharmaceutically acceptable amounts. Exemplary lactose-free dosage forms contain an active ingredient, microcrystalline cellulose, pre-gelatinized starch and magnesium stearate.

Further encompassed are anhydrous pharmaceutical compositions and dosage forms containing a compound provided herein. For example, the addition of water (e.g., 5%) is widely accepted in the pharmaceutical arts as a means of simulating long-term storage in order to determine characteristics such as shelf-life or the stability of formulations over time. See, e.g., Jens T. Carstensen, Drug Stability: Principles & Practice, 2d. Ed., Marcel Dekker, NY, NY, 1995, pp. 379-80. In effect, water and heat accelerate the decomposition of some compounds. Thus, the effect of water on a formulation can be of great significance since moisture and/or humidity are commonly encountered during manufacture, handling, packaging, storage, shipment and use of formulations.

Anhydrous pharmaceutical compositions and dosage forms provided herein can be prepared using anhydrous or low moisture containing ingredients and low moisture or low humidity conditions. Pharmaceutical compositions and dosage forms that comprise lactose and at least one active ingredient that comprises a primary or secondary amine are anhydrous if substantial contact with moisture and/or humidity during manufacturing, packaging, and/or storage is expected.

An anhydrous pharmaceutical composition should be prepared and stored such that its anhydrous nature is maintained. Accordingly, anhydrous compositions are packaged using materials known to prevent exposure to water such that they can be included in suitable formulary kits. Examples of suitable packaging include, but are not limited to, hermetically sealed foils, plastics, unit dose containers (e.g., vials), blister packs and strip packs.

Oral Dosage Forms

Oral pharmaceutical dosage forms are either solid, gel or liquid. The solid dosage forms are tablets, capsules, granules, and bulk powders. Types of oral tablets include compressed, chewable lozenges and tablets which may be enteric coated, sugar coated or film coated. Capsules may be hard or soft gelatin capsules, while granules and powders may be provided in non effervescent or effervescent form with the combination of other ingredients known to those skilled in the art.

In certain embodiments, the formulations are solid dosage forms, such as capsules or tablets.

The composition may also be formulated in combination with an antacid or other such ingredient.

When the dosage unit form is a capsule, it can contain, in addition to material of the above type, a liquid carrier such as a fatty oil. In addition, dosage unit forms can contain various other materials which modify the physical form of the dosage unit, for example, coatings of sugar and other enteric agents. The compounds can also be administered as a component of an elixir, suspension, syrup, wafer, sprinkle, chewing gum or the like. A syrup may contain, in addition to the active compounds, sucrose as a sweetening agent and certain preservatives, dyes and colorings and flavors.

The active materials can also be mixed with other active materials which do not impair the desired action, or with materials that supplement the desired action, such as antacids, H2 blockers, and diuretics. The active ingredient is a compound or pharmaceutically acceptable salt thereof as described herein. Higher concentrations, up to about 98% by weight of the active ingredient may be included.

Pharmaceutically acceptable carriers included in tablets are binders, lubricants, diluents, disintegrating agents, coloring agents, flavoring agents, and wetting agents. Enteric coated tablets, because of the enteric coating, resist the action of stomach acid and dissolve or disintegrate in the neutral or alkaline intestines. Sugar coated tablets are compressed tablets to which different layers of pharmaceutically acceptable substances are applied. Film coated tablets are compressed tablets which have been coated with a polymer or other suitable coating. Multiple compressed tablets are compressed tablets made by more than one compression cycle utilizing the pharmaceutically acceptable substances previously mentioned.

Pharmaceutically acceptable substances used in non effervescent granules, to be reconstituted into a liquid oral dosage form, include diluents, sweeteners and wetting agents. Pharmaceutically acceptable substances used in effervescent granules, to be reconstituted into a liquid oral dosage form, include organic acids and a source of carbon dioxide. Coloring and flavoring agents are used in all of the above dosage forms.

Solvents include glycerin, sorbitol, ethyl alcohol and syrup. Examples of preservatives include glycerin, methyl and propylparaben, benzoic add, sodium benzoate and alcohol. Examples of non aqueous liquids utilized in emulsions include mineral oil and cottonseed oil.

Sources of carbon dioxide include sodium bicarbonate and sodium carbonate. Coloring agents include any of the approved certified water soluble FD and C dyes, and mixtures thereof. Flavoring agents include natural flavors extracted from plants such fruits, and synthetic blends of compounds which produce a pleasant taste sensation.

For a solid dosage form, the solution or suspension, in for example propylene carbonate, vegetable oils or triglycerides, is encapsulated in a gelatin capsule. Such solutions, and the preparation and encapsulation thereof, are disclosed in U.S. Pat. Nos. 4,328,245; 4,409,239; and 4,410,545. For a liquid dosage form, the solution, e.g., for example, in a polyethylene glycol, may be diluted with a sufficient quantity of a pharmaceutically acceptable liquid carrier, e.g., water, to be easily measured for administration.

Alternatively, liquid or semi solid oral formulations may be prepared by dissolving or dispersing the active compound or salt in vegetable oils, glycols, triglycerides, propylene glycol esters (e.g., propylene carbonate) and other such carriers, and encapsulating these solutions or suspensions in hard or soft gelatin capsule shells. Other useful formulations include, but are not limited to, those containing a compound provided herein, a dialkylated mono- or poly-alkylene glycol, including, but not limited to, 1,2-dimethoxymethane, diglyme, triglyme, tetraglyme, polyethylene glycol-350-dimethyl ether, polyethylene glycol-550-dimethyl ether, polyethylene glycol-750-dimethyl ether wherein 350, 550 and 750 refer to the approximate average molecular weight of the polyethylene glycol, and one or more antioxidants, such as butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), propyl gallate, vitamin E, hydroquinone, hydroxycoumarins, ethanolamine, lecithin, cephalin, ascorbic acid, malic acid, sorbitol, phosphoric acid, thiodipropionic acid and its esters, and dithiocarbamates.

In all embodiments, tablets and capsules formulations may be coated as known by those of skill in the art in order to modify or sustain dissolution of the active ingredient. Thus, for example, they may be coated with a conventional enterically digestible coating, such as phenylsalicylate, waxes and cellulose acetate phthalate.

Injectables, Solutions and Emulsions

Parenteral administration, generally characterized by injection, either subcutaneously, intramuscularly or intravenously is also contemplated herein. Injectables can be prepared in conventional forms, either as liquid solutions or suspensions, solid forms suitable for solution or suspension in liquid prior to injection, or as emulsions. In some embodiments, the suspension is a suspension of microparticles or nanoparticles. In some embodiments, the emulsion is an emulsion of microparticles or nanoparticles. Suitable excipients are, for example, water, saline, dextrose, glycerol or ethanol. In addition, if desired, the pharmaceutical compositions to be administered may also contain minor amounts of non toxic auxiliary substances such as wetting or emulsifying agents, pH buffering agents, stabilizers, solubility enhancers, and other such agents, such as for example, sodium acetate, sorbitan monolaurate, triethanolamine oleate and cyclodextrins. Implantation of a slow release or sustained release system, such that a constant level of dosage is maintained is also contemplated herein. Briefly, a compound provided herein is dispersed in a solid inner matrix, e.g., polymethylmethacrylate, polybutylmethacrylate, plasticized or unplasticized polyvinylchloride, plasticized nylon, plasticized polyethyleneterephthalate, natural rubber, polyisoprene, polyisobutylene, polybutadiene, polyethylene, ethylene-vinylacetate copolymers, silicone rubbers, polydimethylsiloxanes, silicone carbonate copolymers, hydrophilic polymers such as hydrogels of esters of acrylic and methacrylic acid, collagen, cross-linked polyvinylalcohol and cross-linked partially hydrolyzed polyvinyl acetate, that is surrounded by an outer polymeric membrane, e.g., polyethylene, polypropylene, ethylene/propylene copolymers, ethylene/ethyl acrylate copolymers, ethylene/vinylacetate copolymers, silicone rubbers, polydimethyl siloxanes, neoprene rubber, chlorinated polyethylene, polyvinylchloride, vinylchloride copolymers with vinyl acetate, vinylidene chloride, ethylene and propylene, ionomer polyethylene terephthalate, butyl rubber epichlorohydrin rubbers, ethylene/vinyl alcohol copolymer, ethylene/vinyl acetate/vinyl alcohol terpolymer, and ethylene/vinyloxyethanol copolymer, that is insoluble in body fluids. The compound diffuses through the outer polymeric membrane in a release rate controlling step. The percentage of active compound contained in such parenteral compositions is highly dependent on the specific nature thereof, as well as the activity of the compound and the needs of the subject.

Parenteral administration of the compositions includes intravenous, subcutaneous and intramuscular administrations. Preparations for parenteral administration include sterile solutions ready for injection, sterile dry soluble products, such as lyophilized powders, ready to be combined with a solvent just prior to use, including hypodermic tablets, sterile suspensions ready for injection, sterile dry insoluble products ready to be combined with a vehicle just prior to use and sterile emulsions. The solutions may be either aqueous or nonaqueous.

If administered intravenously, suitable carriers include physiological saline or phosphate buffered saline (PBS), and solutions containing thickening and solubilizing agents, such as glucose, polyethylene glycol, and polypropylene glycol and mixtures thereof.

Pharmaceutically acceptable carriers used in parenteral preparations include aqueous vehicles, nonaqueous vehicles, antimicrobial agents, isotonic agents, buffers, antioxidants, local anesthetics, suspending and dispersing agents, emulsifying agents, sequestering or chelating agents and other pharmaceutically acceptable substances.

Examples of aqueous vehicles include Sodium Chloride Injection, Ringers Injection, Isotonic Dextrose Injection, Sterile Water Injection, Dextrose and Lactated Ringers Injection. Nonaqueous parenteral vehicles include fixed oils of vegetable origin, cottonseed oil, corn oil, sesame oil and peanut oil.

A sequestering or chelating agent of metal ions include EDTA. Pharmaceutical carriers also include ethyl alcohol, polyethylene glycol and propylene glycol for water miscible vehicles and sodium hydroxide, hydrochloric acid, citric acid or lactic acid for pH adjustment.

The concentration of the pharmaceutically active compound is adjusted so that an injection provides an effective amount to produce the desired pharmacological effect. The exact dose depends on the age, weight and condition of the subject or animal as is known in the art.

The unit dose parenteral preparations are packaged in an ampule, a vial or a syringe with a needle. All preparations for parenteral administration must be sterile, as is known and practiced in the art.

Illustratively, intravenous or intraarterial infusion of a sterile aqueous solution containing an active compound is an effective mode of administration. Another embodiment is a sterile aqueous or oily solution or suspension containing an active material injected as necessary to produce the desired pharmacological effect.

Injectables are designed for local and systemic administration. Typically a therapeutically effective dosage is formulated to contain a concentration of at least about 0.1% w/w up to about 90% w/w or more, such as more than 1% w/w of the active compound to the treated tissue(s). The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at intervals of time. It is understood that the precise dosage and duration of treatment is a function of the tissue being treated and may be determined empirically using known testing protocols or by extrapolation from in vivo or in vitro test data. It is to be noted that concentrations and dosage values may also vary with the age of the individual treated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the formulations, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed formulations.

The compound may be suspended in micronized or other suitable form or may be derivatized to produce a more soluble active product or to produce a prodrug. The form of the resulting mixture depends upon a number of factors, including the intended mode of administration and the solubility of the compound in the selected carrier or vehicle. The effective concentration is sufficient for ameliorating the symptoms of the condition and may be empirically determined.

Lyophilized Powders

Of interest herein are also lyophilized powders, which can be reconstituted for administration as solutions, emulsions and other mixtures. They may also be reconstituted and formulated as solids or gels.

The sterile, lyophilized powder is prepared by dissolving a compound provided herein, or a pharmaceutically acceptable salt thereof, in a suitable solvent. The solvent may contain an excipient which improves the stability or other pharmacological component of the powder or reconstituted solution, prepared from the powder. Excipients that may be used include, but are not limited to, dextrose, sorbital, fructose, corn syrup, xylitol, glycerin, glucose, sucrose or other suitable agent. The solvent may also contain a buffer, such as citrate, sodium or potassium phosphate or other such buffer known to those of skill in the art at, in one embodiment, about neutral pH. Subsequent sterile filtration of the solution followed by lyophilization under standard conditions known to those of skill in the art provides the desired formulation. Generally, the resulting solution will be apportioned into vials for lyophilization. Each vial will contain a single dosage (including but not limited to 10-1000 mg or 100-500 mg) or multiple dosages of the compound. The lyophilized powder can be stored under appropriate conditions, such as at about 4° C. to room temperature.

Reconstitution of this lyophilized powder with water for injection provides a formulation for use in parenteral administration. For reconstitution, about 1-50 mg, about 5-35 mg, or about 9-30 mg of lyophilized powder, is added per mL of sterile water or other suitable carrier. The precise amount depends upon the selected compound. Such amount can be empirically determined.

Topical Administration

Topical mixtures are prepared as described for the local and systemic administration. The resulting mixture may be a solution, suspension, emulsion or the like and are formulated as creams, gels, ointments, emulsions, solutions, elixirs, lotions, suspensions, tinctures, pastes, foams, aerosols, irrigations, sprays, suppositories, bandages, dermal patches or any other formulations suitable for topical administration.

The compounds or pharmaceutically acceptable salts thereof may be formulated as aerosols for topical application, such as by inhalation (see, e.g., U.S. Pat. Nos. 4,044,126, 4,414,209, and 4,364,923, which describe aerosols for delivery of a steroid useful for treatment of inflammatory diseases, particularly asthma). These formulations for administration to the respiratory tract can be in the form of an aerosol or solution for a nebulizer, or as a microfine powder for insufflation, alone or in combination with an inert carrier such as lactose. In such a case, the particles of the formulation will have diameters of less than 50 microns or less than 10 microns.

The compounds may be formulated for local or topical application, such as for topical application to the skin and mucous membranes, such as in the eye, in the form of gels, creams, and lotions and for application to the eye or for intracisternal or intraspinal application. Topical administration is contemplated for transdermal delivery and also for administration to the eyes or mucosa, or for inhalation therapies. Nasal solutions of the active compound alone or in combination with other pharmaceutically acceptable excipients can also be administered.

These solutions, particularly those intended for ophthalmic use, may be formulated as 0.01%-10% isotonic solutions, pH about 5-7, with appropriate salts.

Compositions for Other Routes of Administration

Other routes of administration, such as topical application, transdermal patches, and rectal administration are also contemplated herein.

For example, pharmaceutical dosage forms for rectal administration are rectal suppositories, capsules and tablets for systemic effect. Rectal suppositories are used herein mean solid bodies for insertion into the rectum which melt or soften at body temperature releasing one or more pharmacologically or therapeutically active ingredients. Pharmaceutically acceptable substances utilized in rectal suppositories are bases or vehicles and agents to raise the melting point. Examples of bases include cocoa butter (theobroma oil), glycerin gelatin, carbowax (polyoxyethylene glycol) and appropriate mixtures of mono, di and triglycerides of fatty acids. Combinations of the various bases may be used. Agents to raise the melting point of suppositories include spermaceti and wax. Rectal suppositories may be prepared either by the compressed method or by molding. An exemplary weight of a rectal suppository is about 2 to 3 grams.

Tablets and capsules for rectal administration are manufactured using the same pharmaceutically acceptable substance and by the same methods as for formulations for oral administration.

Sustained Release Compositions

Active ingredients provided herein can be administered by controlled release means or by delivery devices that are well known to those of ordinary skill in the art. Examples include, but are not limited to, those described in U.S. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 3,598,123; and 4,008,719, 5,674,533, 5,059,595, 5,591,767, 5,120,548, 5,073,543, 5,639,476, 5,354,556, 5,639,480, 5,733,566, 5,739,108, 5,891,474, 5,922,356, 5,972,891, 5,980,945, 5,993,855, 6,045,830, 6,087,324, 6,113,943, 6,197,350, 6,248,363, 6,264,970, 6,267,981, 6,376,461, 6,419,961, 6,589,548, 6,613,358, 6,699,500 and 6,740,634, each of which is incorporated herein by reference. Such dosage forms can be used to provide slow or controlled-release of one or more active ingredients using, for example, hydropropylmethyl cellulose, other polymer matrices, gels, permeable membranes, osmotic systems, multilayer coatings, microparticles, liposomes, microspheres, or a combination thereof to provide the desired release profile in varying proportions. Suitable controlled-release formulations known to those of ordinary skill in the art, including those described herein, can be readily selected for use with the active ingredients provided herein.

All controlled-release pharmaceutical products have a common goal of improving drug therapy over that achieved by their non-controlled counterparts. In one embodiment, the use of an optimally designed controlled-release preparation in medical treatment is characterized by a minimum of drug substance being employed to cure or control the condition in a minimum amount of time. In certain embodiments, advantages of controlled-release formulations include extended activity of the drug, reduced dosage frequency, and increased subject compliance. In addition, controlled-release formulations can be used to affect the time of onset of action or other characteristics, such as blood levels of the drug, and can thus affect the occurrence of side (e.g., adverse) effects.

Most controlled-release formulations are designed to initially release an amount of drug (active ingredient) that promptly produces the desired therapeutic effect, and gradually and continually release of other amounts of drug to maintain this level of therapeutic or prophylactic effect over an extended period of time. In order to maintain this constant level of drug in the body, the drug must be released from the dosage form at a rate that will replace the amount of drug being metabolized and excreted from the body. Controlled-release of an active ingredient can be stimulated by various conditions including, but not limited to, pH, temperature, enzymes, water, or other physiological conditions or compounds.

In certain embodiments, the agent may be administered using intravenous infusion, an implantable osmotic pump, a transdermal patch, liposomes, or other modes of administration. In one embodiment, a pump may be used (see, Sefton, CRC Crit. Ref. Biomed. Eng. 14:201 (1987); Buchwald et al., Surgery 88:507 (1980); Saudek et al., N. Engl. J. Med. 321:574 (1989). In another embodiment, polymeric materials can be used. In yet another embodiment, a controlled release system can be placed in proximity of the therapeutic target, i.e., thus requiring only a fraction of the systemic dose (see, e.g., Goodson, Medical Applications of Controlled Release, vol. 2, pp. 115-138 (1984).

In some embodiments, a controlled release device is introduced into a subject in proximity of the site of inappropriate immune activation or a tumor. Other controlled release systems are discussed in the review by Langer (Science 249:1527-1533 (1990). The active ingredient can be dispersed in a solid inner matrix, e.g., polymethylmethacrylate, polybutylmethacrylate, plasticized or unplasticized polyvinylchloride, plasticized nylon, plasticized polyethyleneterephthalate, natural rubber, polyisoprene, polyisobutylene, polybutadiene, polyethylene, ethylene-vinylacetate copolymers, silicone rubbers, polydimethylsiloxanes, silicone carbonate copolymers, hydrophilic polymers such as hydrogels of esters of acrylic and methacrylic acid, collagen, cross-linked polyvinylalcohol and cross-linked partially hydrolyzed polyvinyl acetate, that is surrounded by an outer polymeric membrane, e.g., polyethylene, polypropylene, ethylene/propylene copolymers, ethylene/ethyl acrylate copolymers, ethylene/vinylacetate copolymers, silicone rubbers, polydimethyl siloxanes, neoprene rubber, chlorinated polyethylene, polyvinylchloride, vinylchloride copolymers with vinyl acetate, vinylidene chloride, ethylene and propylene, ionomer polyethylene terephthalate, butyl rubber epichlorohydrin rubbers, ethylene/vinyl alcohol copolymer, ethylene/vinyl acetate/vinyl alcohol terpolymer, and ethylene/vinyloxyethanol copolymer, that is insoluble in body fluids. The active ingredient then diffuses through the outer polymeric membrane in a release rate controlling step. The percentage of active ingredient contained in such parenteral compositions is highly dependent on the specific nature thereof, as well as the needs of the subject.

Targeted Formulations

The compounds provided herein, or pharmaceutically acceptable salts thereof, may also be formulated to be targeted to a particular tissue, receptor, or other area of the body of the subject to be treated, including liposome-, resealed erythrocyte-, and antibody-based delivery systems. Many such targeting methods are well known to those of skill in the art. All such targeting methods are contemplated herein for use in the instant compositions. For non-limiting examples of targeting methods, see, e.g., U.S. Pat. Nos. 6,316,652, 6,274,552, 6,271,359, 6,253,872, 6,139,865, 6,131,570, 6,120,751, 6,071,495, 6,060,082, 6,048,736, 6,039,975, 6,004,534, 5,985,307, 5,972,366, 5,900,252, 5,840,674, 5,759,542 and 5,709,874.

In one embodiment, the antibody-based delivery system is an antibody-drug conjugate (“ADC”), e.g., as described in Hamilton G S, Biologicals, 2015 September, 43(5):318-32; Kim E G and Kim K M, Biomol. Ther. (Seoul), 2015 November, 23(6):493-509; and Peters C and Brown S, Biosci. Rep., 2015 Jun. 12, 35(4) pii: e00225, each of which is incorporated herein by reference.

In one embodiment, liposomal suspensions, including tissue-targeted liposomes, such as tumor-targeted liposomes, may also be suitable as pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art. For example, liposome formulations may be prepared as described in U.S. Pat. No. 4,522,811. Briefly, liposomes such as multilamellar vesicles (MLV's) may be formed by drying down egg phosphatidyl choline and brain phosphatidyl serine (7:3 molar ratio) on the inside of a flask. A solution of a compound provided herein in phosphate buffered saline lacking divalent cations (PBS) is added and the flask shaken until the lipid film is dispersed. The resulting vesicles are washed to remove unencapsulated compound, pelleted by centrifugation, and then resuspended in PBS.

In one embodiment, provided herein is a method of treating, preventing, or managing cancers, inflammatory diseases, rasopathies, and fibrotic disease, comprising administering to a subject a compound provided herein, or a derivative thereof; in combination with one or more second active agents.

As used herein, the term “in combination” includes the use of more than one therapy (e.g., one or more prophylactic and/or therapeutic agents). However, the use of the term “in combination” does not restrict the order in which therapies (e.g., prophylactic and/or therapeutic agents) are administered to a subject with a disease or disorder. A first therapy (e.g., a prophylactic or therapeutic agent such as a compound provided herein, a compound provided herein, e.g., the compound provided herein, or a derivative thereof) can be administered prior to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks before), concomitantly with, or subsequent to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks after) the administration of a second therapy (e.g., a prophylactic or therapeutic agent) to the subject. Triple therapy is also contemplated herein.

Administration of the compound provided herein, or a derivative thereof and one or more second active agents to a subject can occur simultaneously or sequentially by the same or different routes of administration. The suitability of a particular route of administration employed for a particular active agent will depend on the active agent itself (e.g., whether it can be administered orally without decomposing prior to entering the blood stream) and the disease or disorder being treated.

The route of administration of the compound provided herein, or a derivative thereof, is independent of the route of administration of a second therapy. In one embodiment, the compound provided herein, or a derivative thereof, is administered orally. In another embodiment, the compound provided herein, or a derivative thereof, is administered intravenously.

In one embodiment, the compound provided herein, or a derivative thereof, and a second therapy are administered by the same mode of administration, orally or by IV. In another embodiment, the compound provided herein, or a derivative thereof, is administered by one mode of administration, e.g., by IV, whereas the second agent is administered by another mode of administration, e.g., orally.

In one embodiment, the second active agent is administered intravenously or subcutaneously and once or twice daily in an amount of from about 1 to about 1000 mg, from about 5 to about 500 mg, from about 10 to about 350 mg, or from about 50 to about 200 mg. The specific amount of the second active agent will depend on the specific agent used, the type of disease being treated or managed, the severity and stage of disease, and the amount of the compound provided herein, or a derivative thereof, and any optional additional active agents concurrently administered to the subject.

One or more second active ingredients or agents can be used together with the compound provided herein, or a derivative thereof, in the methods and compositions provided herein. Second active agents can be large molecules (e.g., proteins) or small molecules (e.g., synthetic inorganic, organometallic, or organic molecules).

Examples of large molecule active agents include, but are not limited to, hematopoietic growth factors, cytokines, and monoclonal and polyclonal antibodies, particularly, therapeutic antibodies to cancer antigens. Typical large molecule active agents are biological molecules, such as naturally occurring or synthetic or recombinant proteins.

In one embodiment, the compound provided herein, or a derivative thereof, can be administered in an amount ranging from about 0.1 to about 150 mg, from about 1 to about 25 mg, or from about 2 to about 10 mg orally and daily alone, or in combination with a second active agent, prior to, during, or after the use of conventional therapy.

7. EXAMPLES

The following examples are offered to illustrate but not to limit the disclosure.

Example 1 Computational Procedure for Modeling

The protein structures used in this work were obtained from the RCSB PDB (www.rcsb.org).

These structures were prepared for modeling using a suite of structure preparation tools available in the Molecular Operating Environment software (MOE). MOE is a state of the art molecular modeling package licensed by Chemical Computing Group (Molecular Operating Environment (MOE), 2016.08; Chemical Computing Group Inc., 1010 Sherbrooke St. West, Suite #910, Montreal, QC, Canada, H3A 2R7, 2016). It is used extensively in the pharmaceutical industry to carry out a wide range of computer-aided drug design activities. Specifically, each structure was examined for missing atoms and chain breaks. Where possible these were corrected by modeling in incomplete residues or capping. The ligand was also evaluated to ensure the correct structure and bond orders. All titratable residues and the ligand were subjected to Protonate3D (Labute, P.; Protonate3D: Assignment of Ionization States and Hydrogen Coordinates to Macromolecular Structures; Proteins 75 (2008) 187-205) to determine the most probably protonation states at pH 7. Finally, the environment around the ligand was subjected to restrained optimization to remove bad intermolecular contacts and reduce the strain energy for the ligand.

Compounds of interest were modeled in the appropriate binding site using a variety of methods all available in MOE. In many cases the ligands had to be docked into the site. Docking is an automated approach to examine all of the possible ways a ligand might fit into a protein binding site of interest and score the possibilities. These scored structures were used to suggest the best overall protein-ligand complex structure. Docked structures can be evaluated further using other energetic or structural evaluations. In many cases, we also computed the location and contributions of water molecules to binding. This analysis based on 3D-RISM calculations (Luchko, T., Gurasov, S., Roe, D. R., Simmerling, C., Case, D. A., Tuszynski, J., Kovalenko, A.; Three-Dimensional Molecular Theory of Solvation Coupled with Molecular Dynamics in Amber; J. Chem. Theory Comput. 6 (2010) 607-624) can be very helpful for understanding water mediated interactions, and new potential binding sites in the protein that might be exploited with appropriate substitution of the putative ligand.

The ability to build computational models before undertaking their synthesis is a powerful tool for improving the speed and success of drug discovery (Merz, Kenneth M.; Ringe, Dagmar; Reynolds, Charles H., Editors, Drug design: ligand and structure based approaches, Cambridge University Press, 2010).

The docking models displayed in the figures include residues with any atom in close proximity to within a 2.5 angstrom distance from any atom in the ligand. In addition, residues within approximately 2.5 angstroms from the ligand with specific interactions (i.e., a hydrogen bond) are included, and highlighted in the 2D interaction maps.

Example 2 Protocol for MAPK Cell-Based Phosphorylation Assay

Cell lines: Tumor-derived pancreatic cancer cell lines PANC-1 were purchased from ATCC and were maintained according to ATCC recommendation.

Method: Cells were plated at 7500 cells/well density in 96-wells plate, starved over night, and the small molecules to be tested were added to the cells in the final concentration of 30 μM with 0.3% DMSO for 6 hours incubation at 37° C. For IC₅₀ value determination, serial dilutions of compounds were added to cells under the same conditions. Next, cells were stimulated with 1.5 ng/ml EGF for 15 min. followed by cell fixation with 4% Formaldehyde in PBS at RT for 20 min. Phosphorylation level of MAPK was determined by Cell-direct ELISA.

Example 3 Protocol for Cell Proliferation Assay

Cell lines: Tumor-derived pancreatic cancer cell lines MIA-PACA2 were purchased from ATCC and grown in complete DMEM-High Glucose medium supplemented with penicillin (100 U/mL), streptomycin (100 μg/mL), and 10% heat-inactivated FBS at 37° C. in a humidified incubator with 5% CO2.

Method: Cells are plated at 1000 cells/well density in 96-wells plate, starved ON, and the next day tested small molecules are added to the cells in the final concentration of 30 μM with 0.3% DMSO 3 hours prior to 10% FBS addition. After serum addition cells are incubated for 6 days at 37° C. in a humidified incubator with 5% CO₂. For IC₅₀ value determination, serial dilutions of compounds were added to cells under the same conditions.

Assay: At the end of the incubation period, cell cultures are tested using the CellTiter 96® AQueous One Solution Cell Proliferation Assay kit (Promega Corporation, Madison, Wis.) according to the manufacturer specifications. Briefly, assay is performed by adding 20 μl of the CellTiter 96 Aqueous One Solution Reagent directly to culture wells, followed by for 1-4 hours incubation at 37° C. in a humidified incubator with 5% CO₂. At the end of incubation time, absorbance at 492 nm is recorded with the 96-well plate reader Eppendorf AF2200, and degree of small molecule-dependent proliferation inhibition is calculated from raw data assuming No Serum cells value as 100%.

Alternate Assay Conditions

Cell lines: Tumor-derived pancreatic cancer cell lines MIA-PACA2 were purchased from ATCC and grown in complete DMEM-High Glucose medium supplemented with penicillin (100 U/mL), streptomycin (100 μg/mL), and 10% heat-inactivated FBS at 37° C. in a humidified incubator with 5% CO₂.

Method: Cells are plated at 4000 cells/well density in 96-wells plate. The next day tested small molecules are added to the cells in the final concentration of 10 μM in the presence of 0.3% DMSO and 10% FBS. After small molecules addition, cells are incubated for 4 days at 37° C. in a humidified incubator with 5% CO₂. For IC₅₀ value determination, serial dilutions of compounds were added to cells under the same conditions.

Assay: At the end of the incubation period, cell cultures are fixed with a 50-50 mixture (v/v) acetone-methanol for 10 minutes at −20° C., followed by rehydration in PBS for 10 minutes at room temperature. After rehydration, cells are stained with DAPI (1 μg/ml) in PBS for 10 minutes at room temperature, followed by 3 washes with PBS. After staining, DAPI fluorescence is recorded (358 nm excitation/461 nm emission) with the 96-well plate reader Molecular Devices Spectramax M3; degree of small mole-cule-dependent proliferation inhibition is calculated from raw data assuming No Serum cells value as 100%.

Example 4 Protocol for Mouse TNF Alpha and IL6 Quantification Assay

Cell lines: Abelson murine leukemia virus transformed macrophage cell line RAW 264.7 was purchased from ATCC and grown in complete DMEM-High Glucose medium supplemented with penicillin (100 U/mL), streptomycin (100 μg/mL), and 10% heat-inactivated FBS at 37° C. in a humidified incubator with 5% CO₂.

Method: Cells were plated at 40000 cells/well density in a 96-wells plate. After a 3-hour incubation, macrophages were starved with DMEM plus 0.5% FBS o/n. The next day the small molecules to be tested were added to the cells in the final concentration of 30 μM (with 0.3% DMSO) 3 hours prior to LPS stimulation (100 ng/ml). After LPS stimulation cells were incubated at 37° C. for 16h. At the end of the incubation period, culture media were collected and production of LPS-induced TNFα and IL6 cytokine was measured using ELISA detection kits.

Sandwich ELISA: The ELISA Immunoassays Quantikine Mouse TNF-alpha (catalog number MTA00B) and IL6 (catalog number M6000B) were purchased from R&D Systems Inc., Minneapolis, Minn. These 4.5 hours solid phase ELISAs were used to measure mouse TNFα or IL6 levels in macrophages culture supernatants. Assays were executed according to the manufacturer specifications.

Example 5 Ras GTP Binding Domain Inhibition Assay

The following method was developed as specific assay for KRas G12D mutant protein.

Buffer-I:

-   -   50 mM Tris, pH 7.5     -   150 mM NaCl (optional)     -   1 mM MgCl2     -   1 mM DTT.     -   KRas G12D mutant protein was expressed as a His-tagged protein.         Purified His-KRas G12D protein was diluted in buffer-I to a         final concentration of 3-10 μg/ml.     -   200 μl of the diluted His-KRas G12D protein was added to a         nickel coated 96 well plate and incubated overnight at 4° C.     -   The next day, wells were washed 3× in 200 μl of Buffer-I.     -   Then 200 μl of Buffer-I were added to each well in the presence         of 1% DMSO.     -   Tested compounds were added to the protein-coated wells at a         concentration of 20 μM, and incubated for 3 hours at room         temperature. While performing IC₅₀ measurements a serial         dilution of all tested concentrations was prepared.

Then 22 μl of Cy3-GTP or Cy5-GTP was added to each well. The labeled GTP was incubated for 45 min. at room temperature.

-   -   Following GTP incubation, wells were washed 3× in Buffer-I, and         200 μl of Buffer-I were added to each well.     -   Following washes, the amount of bound labeled-GTP was measured         with an Eppendorf AF2200 plate reader.

By substituting KRas G12D mutant protein with KRas G12C mutant, KRas wild type, KRas Q61H mutant, KRas G12D/Q61H double mutant or KRas G12C/Q61H double mutant under the assay conditions described above, KRas G12C mutant KRas wild type, KRas Q61H mutant, KRas G12D/Q61H double mutant and KRas G12C/Q61H double mutant inhibition, respectively, were each determined.
